not sure where it is now, but someone has done the math re: speed/sprocket ratio, but the standard accepted gig is a 44t you'll top out around 30mph, and for each tooth less, add up to one mph. so a 36t should pull you at 37 to 38, provided you have the power. i run a 36t on my racer and it does in fact do a little over 40, but thats with engine modsHey All, I'm planning on getting a either a 32 t or 36t sprocket for my bike.. I'm using the stock 44t right now..
Will the speed gain be great?
32t or 36t?
i really got no hills here in singapore so i guess it should not be a problem for me..
Don't be surprised if your top speed actually does down like on some of my bikes. It's the smooth cruise that's really nice.Will the speed gain be great? 32t or 36t?
DEFINITELY 36t. I had to run my tuned pipe bike with 44t yesterday due to broken spokes on the 36t and it was ridiculous revving at cruise. I'm wishing I had 32t but not for speed.actually i just wanna go faster.. i'll be getting a sbp pipe soon.. so should i use the sbp pipe with 44t or 36t? thx
Firstly, a hill has a LOT to do with it. Secondly, you have it backwards. Pure physics.A hill has nothing to do with it. At some point if the hill is steep enough the 32 will stay in the power longer than a 36 before it winds out.
I find this fun. I have stated why my statement is true. Lets hear yours.Firstly, a hill has a LOT to do with it. Secondly, you have it backwards. Pure physics.
It's quite simple. As the ratio goes down so does torque. And it is torque that makes bikes go not horsepower. You should know this. It is the reason we have reduction in these and don't mount the rear wheel directly to the crankshaft to go 400mph. It is why they don't make 10t rear sprockets.I find this fun. I have stated why my statement is true. Lets hear yours.
Just so you know, I am a ex expert class roadracer in the 600 cc class. I have raced road atlanta, daytona, robeling road, carloina motor sports park and a few more. Each race we changed sprockets for the track and track conditions. I think I know what i'm talking about....or have I been wrong for all these years?
Im all ears! Also re-read post 11, I spelled it out a bit better, wich may have been why we differ on this but I doubt it.
As I've mentioned several times my Zoom slant 66c bikes did beneifit from a 36t. That doesn't make your statements any less ridiculous. BTW I am a professional engineer not armchair. And if anything should be addressed as Dr Armchair as I have completed a doctoral program. Probably before you we born from the sound of things.Haha, Mr Armchair, why dont you put on a 150 tooth sprocket then?
Match the sprocket to the power and duh, you got a winner thats obvious. These motors will pull a 44 tooth and a 28 tooth. You will notice a big difference between the two. Still standing by my armchair, and previous statement.
Some of us are running 66 cc slantheads, with that motor you can tell a difference!
I see you've improved your post a bit. Now that you add "downgrade" the old statement is true but not too relevant. When we talk about hills here it's generally about going UP them. As I mentioned in the other thread it's easy to go downhill at 55-60mph but if the engine is engaged it will most likely sustain damage. For several reasons.A hill has nothing to do with it. At some point if the hill is steep enough (on the down grade) the 32 will stay in the power longer than a 36 before it winds out.
Now if you are building a hill climbing bike a larger sprocket will have more power to get up the hill. The 36 will have more torque to CLIMB and out perform a 32 on a up hill battle.
If you now add the disclaimer "provided you have the power" like Spunout did earlier, we will be on the same wavelength.The smaller the sprocket the faster the top end speed will be
